Problems with cxref in 4.0.3...any fixes?

[Laurence R. Brothers]

I have had the unsettling experience of having about 25% of valid
compilable c code kill cxref. Can anyone recommend a better stand-alone
cross-referencer? I want to know where each identifier is declared,
defined, and used. It would be nice to know whether a usage was on the lhs
or rhs. Oh, and a parse tree and symbol table wouldn't hurt. Hmm, I really
want everything a compiler does, short of code generation, and bared to
the world through readable ascii output.
